Specification of Letters Patent.

Patented Sept. 9, 'i 91 3.

Original application led July 19,1907, Serial No. 384,547. Divided and this application filed June 15,

To all fav/1.0m it may concern llc it known thatl l, OsoAn A.' Ross, a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and uscul Improvements in Valves or the Like, of which the following is a description.

My invention belongs to that general class of devices known as valves and relates particularly to an electropueumatic valve, and has among its objects the production of a simple, efficient, durable and satisfactory device of the Vkind described that is not. easily rendered inoperative and which may be used wherever found applicable.

The device is particularly adapted for use on (luid pressure systems as for example, for signaling devices or automatic railway stop ping devices or the like, but its 'use is not confined to these.

To this end my invention consists in the novel construction, arrangement. and combination of parts herein shown and described and more particularly pointed out in the claims.

1n the drawings wherein like reference characters indicate like or corresponding parts, Figure 1 is a longitudinal sectional view of my preferred form of device showing the valve in closed or normal position, Fig. 2 is a `sectional View of the same taken substantially on line 2 2 of Fig. 41, Fig. 3 is an end elevation of the device, a part removed, Fig. 4 is a sectionalview token substantially on line 4 4 of Fig. l, Fig. 5 is a sectional View of a portion of a sli htly modified construction, and Fig. 6 is a etail View in elevationshowing the locking means for the Casin/gf As before stated, the valwte is particularlyA applicable for railway uses, for example, to automatically set the braksfor give a signal, or both. The operationv of the valve 1s controlled by means of a suitable electrical current which may be controlled by an operator and suitable circuit breakers, as for example, by short circuitingrg` the source of energy, as in the third railsystem, or by an opening of the circuit as in the isolated track rail system, etc. Complete electrical controlling circuit is not shown.

Referring to the drawings in which my preferred form of device is shown, l is a.

Serial No. 566,300.

casing preferably provided with doors which' may contain glass sides or windows 3 if desired. The doors are shown hinged to the casing l, the same being maintained in their closed positions in any suitable way. As most clearly shown in Figs. 1 and G, the doors are provided with extended parts 5 formed as at 6 through which a lock bolt 4: is passed, and il' desired the bolt may be locked in yposition by Ineens or' a padlock 'T or equivalent means. The casing is provided with what may be termed a diaphragm casing or housing 9 extended. as at 8 to afford means for connecting the device to the fluid pressure syste i, as vtor example, to the train line or" the brake system. The housing is shown removably secured to the casing l by means of suit-able bolts 3Q ar# ranged about the flange 3l of the housing. rlhe extended part S is provided with an opening 81 therethrough connecting with a chamber l() in the housing which is connected by an outletl port ll to the chamber 12 opening into the outlet i3. The outlet or port 1l. norinally-covcred or closed and the passage of fluid therethrough controlled by means of a. valve 14 arranged to seat on the valve seat 141. An auxiliary port l5 opening into the outlet 1G may also be provided, and if desired, suitable Whistles 94 and 95 or other signal apparatus he also provided. The signal members or Whistles are connected to the outlets .13 and 16 by means of suitable piping '9G and 97 respec tively, or equivalent. means.

The amount ot air or luid discharged throu h the outlet herea ter described by means of an able plug 17 or its equivalent, which may be locked by a bolt or rod 1'5 passie through the openings 19, 'which to prevent oss or re moval of t le plug by unauthorized ersons, may engage the bolt 4 and he thereby locked thereon when the doors Q are locked in position.

The valve member 14 is provided with a pin 20 arranged to be lever 21 which is e tally carried on a shaft 22 supported by the casing il, a spring 23 or its equivalent; being provided to re slient-ly maintain the valve member on its seat. As shown, the lever 2l is forked and provided with a small extension arranged adjust 1,8 may be regnlateniY as.
